Battery Selection Guide

Our NEW battery selection guide is designed to help you easily find the battery or product to suit your particular vintage electric clock. There were many vintage electric clocks produced over a 50+ year period. We have tried to capture all of the models frequently encountered, as well as a few that we see less frequently. Hopefully you will find your clock listed. If you don’t, please contact us and we will make every attempt to assist you.  If you don’t see the recommended product, contact us for help.

  • Select the manufacturer of your clock
  • Select a Manufacturer

    During the early evolutionary days of electrically-powered self winding clocks, each manufacturer experimented with their own version of the "best" way to power their clocks. There is no "standard" for powering them. We offer a broad range of products to cover as many of these clocks as possible. By selecting the Manufacturer on the left, we will guide you through the choice of battery or other product to power your self winding clock.

  • Monarch - Clock Types
  • Recommended Battery

    Model 1900G-4.5V

    These clocks utilize a single 12 ohm coil requiring 4.5 volts to properly activate winding. They can be adjusted to wind on 3 volts but battery efficiency will suffer. With 4.5 volts, the movement is very reliable, battery life is excellent.

  • Stromberg - Clock Types
  • Recommended Battery

    Avoids use of minute contactor (Recommended)
    Model 1900W-UNV

    Uses minute contactor but must be in good condition (Advanced)
    Model 1900APS

    Like the Standard Electrics, the impulse driven Strombergs can be driven directly to the coil by the Model 1900W-UNV. The Model 1900W-UNV will determine the required, proper voltage and apply it.

  • Recommended Battery

    Single Secondary or Slave Device
    Model 1900W-UNV

    Multiple Secondary or Slaves or two dial Slave Clocks
    Model 1900W-UNV Master-Slave

    High voltage unit provides proper signal to wind clock. Connect directly to coil, bypassing contacts and therefore avoiding effects from burned out contacts (particularly notable with the 110 volt units). Coils are usually marked if unit is 110 volts.
